In order to study the stability and safety of the foundation pit supporting structure system, the wireless tilting vibration sensor is used to discuss the underground monitoring of the underground engineering, the horizontal displacement monitoring of the foundation pit support and the deep foundation pit supporting structure. The actual measured data is compared with the mathematical simulation values. The results show that the foundation pit engineering and shield tunnel engineering can use the wireless vibration tilt sensor for underground engineering monitoring. The width of the foundation pit and the way of excavation are the main factors affecting the internal force and stability of the steel support. With the layered excavation of the foundation pit, the deformation of the retaining structure also has obvious segmental features. The subsection excavation according to the space-time effect can effectively reduce the lateral displacement of the retaining structure. Therefore, for the structural characteristics of underground engineering, the wireless vibration tilt sensor and the method of finite element numerical simulation are combined. The joint support system of steel support and retaining pile has a coordination relationship between deformation and force. The steel support can effectively control the deformation of the envelope structure. When the steel support is erected and 60% of the design axial force value is added, the deformation of the retaining structure can be better reduced. Furthermore, the safety and stability of the structure is increased.

“…Since the wheelchair is moving around constantly, the rollover sensor on the wheelchair should send the information wirelessly for convenience. In some previous works about the wireless tilt monitoring, 7‐9 multiple sensors were involved to get the tilt information, extra wireless modules and external power supplies are needed to realize the function of information transmission, thus they usually have bulky sizes and high costs.…”

This letter proposes an radio frequency identification (RFID)‐based bidirectional wireless rollover sensor for intelligent wheelchair. This sensor consists of two symmetric meandered dipole‐based RFID tags and a tilt switch. The tilt of the wheelchair can be recognized directly by the chip code received by the RFID reader and no data postprocessing is needed, so it could be used to detect the rollover status and activate rollover protective measures of the intelligent wheelchair. Meanwhile, emergency signal containing the location of the fallen wheelchair can also be sent to the hospitals or aid stations nearby through the RFID reader. A typical application scenario of the sensor has been proposed, modeled, and analyzed. Simulations and measurements of the sensor in this scenario have been carried out to validate its performance.
